DETAILED DESCRIPTION OF THE DRAWINGS

The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to the precise form disclosed. Rather, the embodiments selective for description have been chosen to enable one skilled in the art to practice the invention.

Referring initially to FIGS. 1-3, an illustrative faucet 10 of the present disclosure is shown coupled to a mounting deck, illustratively a sink deck 12 surrounding a sink basin 14. As further detailed herein, the illustrative faucet 10 includes a hub 16, a hose 18 having a first or inlet end 20 operably coupled to the hub 16, and a wand or sprayhead 22 fluidly coupled to a second or outlet end 24 of the hose 18.

Illustratively, a mounting shank 26 and a cooperating nut 28 couple the hub 16 to the sink deck 12 (FIG. 1). The hub 16 illustratively includes a passageway 29, and supports a conventional mixing valve 30 including a movable valve member (not shown) operably coupled to a handle 32. Hot and cold water sources 34 a, 34 b are illustratively fluidly coupled to the mixing valve 30 via supply conduits (illustratively, flexible tubes) 36 a, 36 b, respectively (FIG. 8). As is known, rotation of the handle 32 about a first axis 38 (as shown by arrows 40 in FIG. 2) controls water temperature to a water outlet 42 defined by the sprayhead 22. Similarly, rotation of the handle 32 about a second axis 44 (as shown by arrows 46 in FIG. 2) controls water flow rate to the water outlet 42.

A swing arm 48 is rotatably supported by the hub 16. More particularly, a first end 50 of the swing arm 48 is rotatably coupled to the hub 16 by a swing arm rotatable coupling 52. As shown in FIG. 3, the swing arm pivot coupling 52 is configured to permit rotation of the swing arm 48 about an upwardly extending longitudinal axis 54 of hub 16. The sprayhead 22 is releasably coupled to a second end 56 of the swing arm 48.

With reference to FIGS. 4 and 5, an inlet end or first pivot coupling 58 is configured to permit rotation of the first end 20 of the hose 18 relative to the hub 16 and the swing arm 48. As shown in FIGS. 3 and 4, the first pivot coupling 58 is configured to rotate the first end 20 of the hose 18 about the longitudinal axis 54. An outlet end or second pivot coupling 60 is configured to permit rotation of the sprayhead 22 relative to the second end 24 of the hose 18. As shown in FIGS. 3 and 4, the second pivot coupling 60 is configured to rotate the sprayhead 22 about an upwardly extending longitudinal axis 64 of the sprayhead 22.

As further shown in FIG. 3, the swing arm 48 may rotate relative to the hub 16, and independently of the hose 18 and the sprayhead 22. In the illustrative embodiment, the first pivot coupling 58 is configured to permit the swing arm 48 to rotate independent of hose 18. The swing arm 48 may rotate independent of the sprayhead 22 because the sprayhead 22 releasably couples to the second end 56 of the swing arm 48. In this way, a user may rotate the swing arm 48 about the longitudinal axis 54 of hub 16 without likewise moving the sprayhead 22.

Additionally a user may rotate the swing arm 48 about the longitudinal axis 54 of the hub 16 in a first direction (e.g., clockwise) via the rotatable coupling 52, while moving the sprayhead 22 in a second direction opposite the first direction (e.g., counterclockwise) via the second pivot coupling 60. Moreover, a user may retain the sprayhead 22 on the second end 56 of swing arm 48 and rotate both the sprayhead 22 and the swing arm 48 in the same direction together or in opposite directions.

As shown in FIGS. 4 and 5, a releasable coupler, such as a magnetic coupler 66, illustratively releasably couples to the second end 56 of swing arm 48 to the sprayhead 22. The magnetic coupler 66 illustratively includes a magnet 68 supported by the second end 56 of the swing arm 48, and a metal washer 70 supported by the sprayhead 22. A variety of different couplings may releasably couple the sprayhead 22 to the second end 56 of swing arm 48, including, for example, flexible retaining fingers, bayonet couplings, etc.

With reference to FIGS. 4 and 5, the hose 18 illustratively comprises an outer sheath 72 that receives an inner waterway 74. In the illustrative embodiment shown, the outer sheath 72 includes a non-circular shaped transverse cross-section. More particularly, the outer sheath 72 has a polygonal shaped transverse cross-section, illustratively a rectangular shaped transverse cross section. Additionally, outer sheath 72 may be molded from a flexible material, such as a thermoplastic elastomer (TPE). Illustratively, the outer sheath 72 may be formed of a thermoplastic vulcanizate (TPV), such as Santoprene™, available from United States Plastic Corp. of Lima, Ohio.

The inner waterway 74 illustratively comprises a cylindrical tube. This cylindrical tube may be formed from a flexible material, such as a polymer. Illustratively, the inner waterway 74 is formed of a cross-linked polyethylene (e.g., PEX). As shown in FIG. 5, the inner waterway 74 may include first and second portions 74 a and 74 b fluidly coupled together with a conventional barbed connector 75. Alternatively, the inner waterway 74 may be formed as a single component. Illustratively, the structural and material properties of the hose 18 permit bending of the outer sheath 72 and the inner waterway 74 about axes extending perpendicular to the longitudinal axis of the hose 18, and permit twisting of the outer sheath 72 about the longitudinal axis of the hose 18.

With reference to FIGS. 4-6A, the first pivot coupling 58 illustratively includes a circular recess 78 within the first end 50 of the swing arm 48 receiving a first adapter, illustratively a rotatable housing 80. More particularly, the circular recess 78 illustratively includes an upper bore 82 having a first inner diameter, and a lower bore 84 having a second inner diameter, the first inner diameter being greater than the second inner diameter. The housing 80 illustratively extends axially between an upper portion 86 received within the upper bore 82, and a lower portion 88 received within the lower bore 84 (FIG. 4).

The upper portion 86 of the housing 80 is coupled to the outer sheath 72 at the first end 20 of the hose 18. A bore 90 extends axially along a centerline of the housing 80 and receives the inner waterway 74 of the hose 18. The upper portion 86 of the housing 80 includes an upper surface 92 and a lower surface 94. A hose recess 96 extends downwardly from the upper surface 92 for receiving the outer sheath 72 of the hose 18. Conventional fasteners, such as bolts 98, may be received within openings 99 in the outer sheath 72 to secure the outer sheath 72 to the upper portion 86 of the housing 80. With reference to FIG. 6A, a first adapter width (aw1) is defined by an outer periphery of the upper portion 86 of the housing 80, and a first end hose width (hw1) is defined by an outer periphery of the first end 20 of the hose 18. The first adapter width (aw1) is illustratively greater than the first end hose width (hw1).

With reference to FIGS. 4, 5 and 6B, the second pivot coupling 60 illustratively includes a circular recess or opening 100 within the sprayhead 22 receiving a second adapter, illustratively a rotatable disc 102. A bore 104 extends axially along a centerline of the disc 102 and receives the inner waterway 74 of the hose 18. The disc 102 is illustratively coupled to the outer sheath 72 at the second end 24 of the hose 18. The disc 102 illustratively includes an upper surface 105 and a lower surface 106. A hose recess 108 extends downwardly from the upper surface 105 for receiving the outer sheath 72 of the hose 18. Conventional fasteners, such as bolts 110, may be received within openings 111 in the outer sheath 72 to secure may secure the outer sheath 72 to the disc 102. A second adapter width (aw2) is defined by an outer periphery of the disc 102, and a second end hose width (hw2) is defined by an outer periphery of the second end 24 of the hose 18. The second adapter width (aw2) is illustratively greater than the second end hose width (hw2). The inner waterway 74 is illustratively coupled to the sprayhead 22 by a retaining clip 112 and an o-ring 114.

The illustrative sprayhead 22 further includes a user interface, such as a toggle or rocker switch 116. Illustratively, a user may operate the switch 116 to change the characteristics or modes of water exiting the outlet 42. For example, the switch 116 may move a diverter valve (not shown) between an aerated stream mode and a spray mode. More particularly, and with further reference to FIG. 4, the outlet 42 may include an aerated stream outlet 118 (defining the stream mode) and a plurality of sprayer outlets 120 (defining the spray mode).

As noted above, the sprayhead 22 also illustratively includes a magnetically attractive member, such as the metal washer 70, which magnetically engages with the magnet 68 to magnetically couple the sprayhead 22 to the second end 56 of swing arm 48. The metal washer 70 may concentrically surround second pivot coupling 60 and define the opening 100, as shown in FIGS. 4 and 5. A nest 122 is illustratively supported by the second end 56 of swing arm 48. The nest 122 supports the magnet 68 for releasably supporting and coupling the sprayhead 22. As shown in FIG. 4, a retainer, such as a resilient finger or tab 124, is illustratively received within an opening 126 to secure the nest 122 to the swing arm 48.

With reference to FIGS. 5 and 7, the swing arm rotatable coupling 52 between the swing arm 48 and the hub 16 illustratively includes a spout tube 130 coupled to the first end 50 of the swing arm 48. Illustratively, the spout tube 130 is fixed to the first end 50 of the swing arm 48 by conventional fastening means, such as threads and/or adhesives. A retainer 132 receives the spout tube 130, and is supported between the spout tube 130 and the hub 16. Upwardly extending posts 134 of the retainer 132 are secured within openings 136 formed within the swing arm 48 (FIG. 7). The retainer 132 is supported within the passageway 29 of the hub 16 for rotation therebetween.

With reference to FIGS. 8 and 9, a further illustrative inlet end or first pivot coupling 138 illustratively includes many similar features to the pivot coupling 58 identified above. As such, similar components will be identified with like reference numbers. The illustrative first pivot coupling 138 of FIGS. 8 and 9 includes a modified adapter or housing 80′ including an upper portion 86′ and an extended lower portion 88′ received within the spout tube 130 and retained by a clip 140. More particularly, the clip 140 is retained within a groove 142 formed in the lower portion 88′ of the housing 80′.

With reference to FIGS. 10 and 11, a further illustrative outlet end or second pivot coupling 144 illustratively includes many similar features to the pivot coupling 60 identified above.

Engagement between the tab 146 and the groove 148 assists in retaining the outlet end 24 of the hose 18 within the sprayhead 22.

With reference to FIG. 12, an actuator driven valve 150, illustratively an electrically operable valve, may be fluidly coupled in series with the mixing valve 30. Illustratively, a controller 152 is electrically coupled with the actuator driven valve 150. The controller 152 is configured to control the opening and closing of the actuator driven valve 150, and therefore to control the flow of water from the mixing valve 30 to the outlet 42 of the sprayhead 22. A user input, illustratively a capacitive sensor 154, is electrically coupled with the controller 152 and with the hub 16. Other types of user inputs may be substituted for the capacitive sensor 154, such as infrared sensors.

In the illustrative embodiment of FIG. 12, a capacitive coupling 156 is positioned between the hub 16 and the swing arm 48. As such, the capacitive sensor 154 is operably coupled to the hub 16 and to the swing arm 48 (through the hub 16 and the capacitive coupling 156). The handle 32 is also electrically coupled to the capacitive sensor 154. The hub 16 and the swing arm 48 are illustratively formed of an electrically conductive material such as a plated metal, such that contact with (or close proximity to) the hub 16 and/or swing arm 48 from a user is detected by the capacitive sensor 154.
